ANTTSLIPPING- DEVICE FOR HOli-SESHOES.

Specification of Letters Patent.

Application filed July 16, 1912.

Patented Oct. 7, 1913.

Serial No. 709,621.

To all whom it may concern.

Be it known that 1, WILLIAM F. SMYTHE, a citizen of the United States, residing at 327 West Thirty-fourth street, borough of Manhattan, city, county, and State of New York, have invented new and useful Improvements in Antislipping Devices for Horseshoes, of which the following is a specification.

This invention relates to anti-slipping devices adapted to be attached to horses shoes to assure that they will have a good footing on slippery or icy roads.

One of the objects of the invention is to provide a device of this character which is adjustable and can be applied to horse shoes of diflerent lengths and widths.

Another object of the invention is to provide a device which may be easily attached to or removed from the shoe and which when attached to the shoe will be firmly held thereon.

Another feature of the invention is to provide a device of this character in which the calks may be readily removed if it is desired to replace them with other calks or to sharpen them.

Other objects of the invention will in part be obvious and in part be pointed out hereinafter.

In the accompanying drawings showing an illustrative embodiment 'of the invention and in which the same reference numeral refers to similar parts in the several figures, Figure 1 is a view in side elevation showing the device applied to a horse shoe. Fig. 2 is a bottom plan view of Fig. 1. Fig. 3 i a sectional view taken on the line 33 of Fig. 1 looking in the direction of the arrows.

Referring to the drawings, 1 represents a horse shoe of any known form and construction, and is shown as applied to the hoof of a horse. The anti-slipping device or supplemental shoe, which conforms to the shape of the horseshoe, comprises two front plates 2 and 3 and two rear plates 4 and 5. As shown in Fig. 1 the rear portions of front plates lie under the front portions of the rear plates and the front portions 6 thereof are bent upward in order that the upper surfaces thereof will lie in substantially the same plane as the upper surfaces of the rear plates. The

front plates 2 and 3 are provided with slots 7 extending lengthwise thereof, which slots receive the shanks of the threaded bolts or the like '8 which engage suitable holes in the rear plates 4 and 5 and nuts 9 engage the threaded end portions of the bolts 8. From this construction it will be apparent that by loosening the bolts 8 the front plates may be moved back and forth with respect to the rear plates whereby the de vice may be adjusted for horse shoes of different lengths.

One of the front plates 3 is provided with a downwardly turned, laterally extending flange 10 which is preferably made integral therewith and this flange is provided with slots 11. The other front plate 2 has so cured thereto, as by rivets, a laterally extending flanged member 12, the flange of which is spaced from and lies parallel with the flange 10 and is provided with slots 13 registering with the slots 11 in the flange 10. A piece of metal 14 is riveted or otherwise secured to plate 3 with its forward edge adapted to slidingly engage the flanged member 12 whereby to guide the latter. The flanges l0 and 12 form brackets between which the calks 15 are positioned, being held in place by bolt or the like 16 which pass through the calks and through the slots 11 and 13 and are held in position by nuts 17. Each of the front plates 2 and 3 is also provided with an upwardly extending portion 18, preferably formed integral with the plate, which por tions engage the outer edge of the horse shoe and assist in holding the supplemental shoe in position.

From the above description it will be understood that by loosening the nuts 17 of the bolts 16 the plates forming one side of the supplemental shoe may be moved toward or away from the plates forming the other side whereby the supplemental shoe may be'readily adjusted to fit horse shoes of various widths. After being adjusted to the desired width the nuts 17 are tight .ened thereby holding the parts firmly in their adjusted positions. It will also be understood that the calk 15 may be moved toward or away from one another if desired, by reason of the fact that the bolts 16 are positioned in slots 11 and 13. If

it is desired to remove the calk to sharpen it or to replace it by another calk it is, of course, merely necessary to remove the nut 17 and withdraw the bolt 16.

Each of the rear plates 4, and 5 i provided at its rear end with a downwardly turned portion 19 preferably integral with the plate, and is further provided with an angle member 20 which is rigidly secured to the plate and is spaced from the dowir wardly extending portion 19 a distance sufficient to receive a calk 21. The downwardly extending portion 19 and the angle member 20 form brackets between which the calk is held in any suitable manner as by means of a bolt 22 and nut 23. Each of the rear plates is also provided with an upwardly extending portion 24:, which is adapted to engage the outer surface of the shoe to assist in holding the supplemental shoe in position.

From the above description it will be understood that the supplemental shoe may be adjusted as to. its length and also as to its width in order that it may be adapted to horse shoes of different sizes and it will also be seen that the calks which are firmly held in position may very readily be removed if their removal is desired for any purpose.

The means of attaching the supplemental hoe to the horse shoe will now be described.

The rear plates 4 and 5 are provided with inwardly extending lugs 25 to which are pivoted the rear ends of the upper clamping plates 26. These clamping plates are bent upwardly as indicated at 27 whereby they are adapted to engage the upper surface of the horse shoe as clearly shown in Fig. 3. Pivotally secured to the front ends of the upper clamping plates which extend substantially throughout the length of the supplemental shoe, are links 28, which links are provided with slots 29 adapted to receive a bolt or the like 30.

It will be observed that the links 28 form a toggle joint between the forward ends of the upper clamping plates 26. The bolt 30 also passes through a perforation formed in the lower clamping plate 31 the ends of which are adapted to engage the under surface of the supplemental shoe. A spacing member 33 is provided, if necessary, between the links 28 and the clamping plate 31 and a nut 82 engages the threaded. end of the bolt for holding the parts against movement. The object of the slots 29 in the links 28 is to provide the necessary adjustment whereby the clamping plates 26 may engage the upper surface of the horse shoes of different widths, and they also assist in removing the supplemental shoe from the horse shoe or in attaching it thereto.

The operation of the device which should be largely obvious from the drawings is as follows: Assuming the supplemental shoe to be in position upon the horse shoe as shown 7 in the drawing, if it is desired to remove the same it is merely necessary to loosen the nut 32 which engages the bolt 30 and 7 movement will, of course, cause the front ends of the upper clamping plates 26'to move inward, thereby freeing these plates from engagement with the horse shoe, after which the supplemental shoe may, of course, be removed. To place the device'upon the horse shoe the steps are substantially the reverse of those just described, The sup-' plemental shoe is placed in position rela-' tively to the horse shoe, the clamping plates 26 being in their inner position, and pressure is applied to the bolt 30 and the parts connected thereto to move the same toward the front of the shoe, which movement will cause the plates 26 to move outward and into engagement with the upper surface of the horse shoe. At the same time the lower clamping plate will be moved into engagement with the lower surface of the supplemental shoe. When thus positioned, the nut 30 is tightened in order that relative movement of the parts may be prevented, and the supplemental shoe is firmly attached to the horse shoe.

Having described this invention in connection with the illustrative embodiment thereof, to the details of which disclosure the invention is not, of course, to be limited, what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims: a

1. In a supplemental horse shoe, in combination, a side plate comprising a laterally extending downwardly projecting flange, a second side plate provided with a laterally extending downwardly projecting flange overlapping said first mentioned flange, said flanges being spaced from one another and in parallelism with one another, a calk interposed between said flanges, and means for holding said calk in positionand said side plates from relative movement,

2. In a supplemental horse shoe, in combination, a sideplate provided with a laterally extending downwardly projecting flange, a second side plate provided with a laterally extending downwardly projecting flange, said flanges over-lapping one another and being in parallelism" with one an- 3.
